> Where it falls down is like anything else like this: it basically requires that all the things you dep on also adhere to this philosophy and have nix setups already or you'll be in a world of pain rolling your own. I gave up on converting our $work stuff when it became clear that the versions of flatbuffers and a few other deps we depend on just weren't out there in the nix ecosystem and I wasn't going to volunteer to make them.

Maybe I'm a bad NixOS user, but I tend to run most of my development work through steam-run, unless the necessary default.nix is really simple. It works fine, and having the rest of the system be immutable is still an advantage.
